河南省淇县土壤硒元素分布特征及其影响因素
Distribution characteristics and influencing factors of soil selenium in Qi County,Henan Province
摘要
Abstract
With a soil geochemical survey in the Qi County area of Henan Province,we collected 721 topsoil samples(0-20 cm)and 30 wheat grain samples.Using modern analytical techniques,we systematically characterized the geochemical behavior of soil selenium(Se)and its relationships with key soil physicochemical properties.The results show that the mean Se concentration in topsoil of the study area is 0.39×10-6,and the area of Se-enriched land reaches 32.30 km2,indicating substantial potential for the development of Se-rich land resources.Soil organic matter,germanium,and strontium contents all exhibit significantly positive correlations with Se concentration,whereas the soil pH shows a weak negative correlation.Wheat grains demonstrate a high Se enrichment rate,and the Se concentration in wheat grain is positively correlated with that in the corresponding rhizosphere soil,pointing to promising prospects for Se-enriched agricultural development in the region.关键词
